Using a Multi-meter and Testing Wires
i
A digital multi-meter is your safeguard when doing a motorcycle alarm. Testing wires before you
make a connection is a sure fire way to make sure you are making a proper connection. Your multi-
meter should have a DC setting with 2 leads, red and black: positive (+) and negative (-).
Testing Wires
When installing any electrical component into a vehicle, you will have 3 polarities which you may
need to test for. There are positive, negative and reverse polarity configurations which you must
know how to test for.
Positive (+)
When testing for a wire which should have a positive polarity, you will need to do as follows. Set
your multi-meter to 12Volts DC. Connect your black lead to chassis ground (-). Next connect your
red lead to the wire which you believe has 12volts. The meter will show 12V if that wire is positive.
The meter will show 0 if it is not.
Negative (-)
When testing for a wire which should be negative (grounded), you will need to do as follows. Con-
nect the red lead from your meter to 12volts constant (+). Connect the black lead to the wire you
believe is grounded. The meter should show 12V if that wire is grounded. It will show 0 if it is not.
Specific Testing Applications
Ignition Wires
12Volts with key in all positions except for ʻoffʼ
Testing an ignition wire is simple. Ignition wires are generally positive in polarity. Start by setting
your meter to DC 12V. Next, take your black lead and put it to chassis ground (-). Next, connect the
red lead to what you believe to be the ignition wire in the vehicle. It should show 0 Volts when the
key is off. Next, cycle the key through the Accessory and Ignition position. It should show 12Volts
in both positions. Next, crank and run the vehicle. It should show power even while cranking. If it
does, it is an ignition wire. If not, please read “testing an accessory wire” below. Ignition Wires are
used for motorcycles alarm and remote Starting.
Accessory Wires 12Volts with key in all positions except off and crank
Testing an accessory wire is the same as testing an accessory wire. The only exception is the meter
should show 12volts with the key in the accessory and ignition positions only. There should be 0
volts in the off and crank position. Accessory wires are used in remote starting Installations, and are
especially important on bikes with EFI.
Starter Wires 12volts ONLY in crank position
Testing a starter wire is very simple. Start by locating the suspected wire in the vehicle. Next, take
your meters black lead and connect it to ground. Next, connect the red lead to the wire you believe
